I can do but again, I don't think they care.

On ARM at least, we don't document the board compatibles because this
will be a huge list without much benefit as they are mostly unused.
Still, it is nice to have in case something specific needs to be done
for a particular board (and hopefully this never happens).

also, I don't think any other MIPS boards are documented bu if you
insist, I can either add it in
Documentation/devicetree/bindings/mips/mscc.txt or create a new file to
list all the mips board compatibles.
